the glass materials are different, and the appearance quality is also different. The glass below 10 yuan is basically ordinary glass, and toxic substances will be precipitated in the water for a long time. Generally, those with more than ten yuan are high borosilicate glass for foreign trade. This kind of glass is non-toxic and harmless. Foreign baby bottles are made of this kind of glass
the quality requirements for foreign trade exports are relatively high. Drinking water in glasses is the healthiest, but you should choose glasses made of high-quality glass materials
the glass does not contain organic chemicals during the firing process. When people drink water or other drinks with glass, they need not worry that chemicals will be drunk into the stomach. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall. Therefore, it is the healthiest and safest for people to drink water with glass
glasses are divided into two types of glass:
crystal glass refers to crystal works made of artificial crystals of various colors (containing 24% lead dioxide) as raw materials and dewaxed at high temperature by the ancient bronze dewaxing casting method
its color is flowing clouds and beautiful wheels; Its quality is crystal clear and dazzling. This process needs dozens of manual and careful operations to complete, and a little negligence can cause failure or defects. The heavy metal is lead dioxide. But now the lower price is generally imitation glass, water glass, resin or crystal glass
crystal cup: it is divided into natural crystal and artificial crystal. Natural crystal should be very good, and its natural health function is very good. Anyway, I think so. In the case of artificial crystal, artificial crystal is high lead glass, or lead crystalline glass, that is, adding 24% lead oxide to ordinary glass (containing silicon dioxide) will obtain artificial crystal with brightness and transparency similar to natural crystal
The glass materials are different, and the appearance quality is also different. Basically, the glass below 10 yuan is ordinary glass, and toxic substances will be released in the water for a long time. The glass above 10 yuan is generally high borosilicate glass specially used for foreign trade. This kind of glass is non-toxic and harmless. Foreign baby bottles are made of this kind of glass. You can also ask me if you have any questions. I used to work in glass export
This is mainly due to the glass material and manufacturing process. Some cheap glasses may be made of recycled materials, which may contain heavy metals harmful to human body. Some glasses have poor manufacturing process and are easy to be damaged. Generally, it is best to choose brands with quality assurance. For example, for some heat-resistant and moisturizing glass, the raw materials of its products are more than a few yuan, and the finished products are of course more expensive. It is impossible for it to be cheaper than the cost after it is produced, that is, as the saying goes, every penny is worth every penny.
It's obvious when you compare the two! There will be a lot of small defects and spots on the 3 yuan! The cup is not so smooth! I haven't heard about my health!
